The springs are of general S-shaped configuration and shock absorbers disposed at an angle of approximately 40 DEG to 50 DEG to the vertical or mounted for disposition between the frame and midsection for coordinating with the springs for minimizing forceful, normally damaging impact upon the spray boom assembly through vehicle travel over irregular terrain.
